Application filed Elm/ember To all whom it may concern.-

Be it known that I, ENoon A. BAKER, a citizen of the United States of America, and a resident of Nillimansett, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Apparatuses for Cleaning Boilen Flues, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for cleaning out the smoke-fines of steam-boilers, and more especially to the kind in which steam supplied from the boiler is employed from time to time for Clearing away the soot and ashes or einders collected in the fines.

An object of the invention is to provide an apparatus which is of such simple and inertpensive construction and of such easy application in conjunction with ordinary boilers as to be unusually elficient and'dcsirable.

The invention consists in the combination, with a flue-boiler, of apipe extended horizontally through and rotative in the setting, a supply-pipe receiving steam from the boiler and connected with said rotative pipe, and

' said latter pipe carrying an angular ndwiseclosed pipe-section revoluble in a vertical plane'and located within the setting and between it and the end of the boiler and having a series of steam-delivery perforations through its side toward the mouths of the flues, the location or" the improved device being preferably at the rear of the furnace, so that the clearin of the soot or other accumulations in the boi er-flues will be forwardly and in a direction with the draft through the fines to be carried away through the smoke-stack.

The invention furthermore consists in cer-' tain particular formations of parts and the combination and arrangement of the parts and all substantially as herein shown and described.

in the accompanying drawings, Figure 1 is a sectional elevation from front to rear through a boiler, its setting, and a furnace. Fig: 2 is a sectional elevation as seen looking forwardly beyond the plane indicated by the line 2 2, Fig. i. Fig. 3 is an elevation at the rear of a boiler-furnace, M

Similar characters of reference indicate corresponding parts in all of the views;

In the drawings, A represents a horizontal steam-boiler mounted in the setting or housing B therefor, of which a is the rear end wall, a space or chamber bexisting between the rear end of the boiler and the end wall a of Specification of Letters Patent.

the housing or setting, into which the prod: nets of combustion from the boiler-furnace C may pass and thence through the fiues d to the smoke-stack. The wall of the setting or housing is made with an aperture horizontally therethrough axially coincident with the center of the boiler, in which is a metallic thimble or bushing e. The horizontal section D is extended horizontally through and .is adapted to have a rotative motion in said bushing, and it carries at its inner end in the space 5 to the rear of the boiler a pipe-section E, which by an elbow-coupling f is connected at right angles with the horizontal rotative tional movements of the pipe E a revoluble motion around and across the semicircular lower portion of theboiler, in'which portion the dues are distributed. The lower end of the pipe-section E is closed, as by the cap 9 toward the end of the boiler are the series of tensions, as indicated at 7L2, beinga vantageously provided.

G represents the steam-supply pipe lead: ing from the dome of. the boiler, as illustrated in the present instance, and this supply-pipe has a vertical section 'l, in an intermediate portion of which is a T-coupling j with a coupling-limb in line with the rotative pipe D, and a short coupling m is connected or jointed to the pipe D, so that the latter may have its rocking or rotative movements independently of the steam-supply conduit and yet maintaining a tight steamway. n represents a valve in the supply-pipe above the connection therewith of; the pipe D, so that when opened dry steam from the dome of the boiler may pass to issue through the jet-hole 7t 71 to be directed into all of the hues of the boiler which are in a radial line corresponding to the length of the pipe-section E, winch has its traversing swinging movement across the face of the lower half of the boiler end in a vertical plane, it being perceived that the pipe E has j et-holes in greater and such holes are in closer proximity than the spacing of the dues, so that when the pipe is positioned to deliver steam, say through one-haliof the jets, into one radial line of fines at one time, a diii'eren t positioning of the pipe will cause the steam issuing fronrthe relatively intermediate j et-holes pipe and has in conjunction with the rota-- number than that of any radial line of fluesj or otherwise, and through the side of the pipe perforations or steam-jet holes h, nip le expipe-section j by the unionsee,

= into the fines found in'another radial r beans for conveniently swinging the b so E, iccom lished by the rocking or arrotating of the pipe l), and one whic is rely operable from the back of the houssetting, a lever-handle J is affixed to B, through the operation of which neer may gradually change the poof the pipe E until it has been brought portions of the line comprising boner. ower portion of the depending soctne steam-supply pipe and below the therewith of the pipe D is a dripby the opening of which, after the apmay have been used and the valve sod, any accumulations of water from r i condensation may be discharged, or the e trial discharge of such accumulations by slightly opening the valve m and c the steam-pressure to force out'the d water. Then for the flue-cleaning on the clrip-coclq is closed'and the t re a is widely opened and the lever ati're to sucicessively position the "a for a forcible steam delivery e lines, forcing soot and other fines to be carried natural draft to the that when in disuse the jet-pipe be subjected to the most intense from the furnace, the same may be swans upwardly to the position represented in l hrough means of the lever, which is such position by a keeper or hook .ed and arranged to detachably engage the lever. 4o

.ving thus described invention, what 1, and desire to secure by Letters Patent, is

.. ne combination with a flue-boiler, of a pipe, and a support for said pipe adj scent the end of the. boiler, relative y. to which the rotative onan axis arallel with the eng'th of the boiler, a su. p y-pipe receiving from the boiler an connected to said rotativs pipe, and said latter carrying an angularly--e:rtended, endwise-closed, pipesection revoluble in a lane parallel with, and adjacent, the end of t e boiler, and having a series 01"- steam-delivery perforations through its side toward the mouths of the boiler-fines.

2. The combinati'on with a horizontal flueboiler and its setting, of a pipe extended horizontally through, and rotative in, the

"setting on an axis parallel with the length of the'end of the boiler, and having a series of steanrdelivery perforations through its side toward the mouths of the fines, a'valve for controlling the admissionol steam through the said supply-pipe, and means externally of the setting for turning said rotatiye pipe.

The combination with a horizontal flueboiler, of a pipe horizontally and rotatably mounted behind the end of the boiler and having its length parallel with the axis of the boiler, a supply-pipe receiving steam from the boiler and iaving a vertical section, an intermediate part of which is in communication with said rotative pipe, and said latter carrying an angular endwise-closedpipe-seo tion revoluble in a vertical plane arallel with the end of the boiler and located within the setting and between it and the end of the boiler, and having a series of steam-delivery perforations through its side toward the mouths of the fines, means for turning the horizontal pipe, a valve in said vertical pipesection above the horizontal rotatable pipe, and a drip-cock in said 'vcrtical pipe-section below the rotatable pipe.

4. The combination with a flue-boiler and its scttingprovided with a tubular metallic. bushing, of a pipe extended horizontally through, and rotative in said bushing 01' the the boiler an a union-coupling connecting said supply-pipe and said rotative pipe, and

closed pipe-section revoluble in a vertical plane and located within the setting and b0- tween it and the end of the boiler, and-having a series of steanudclivery perforations through its side toward the mouths of the fines, a valve for controlling the admission of steam through the supply-pipe, and a handle externally ol the setting provided to the rotative pipe and for turning the latter.

its setting, of a pipe extended horizontally through, and rotative in, the setting, a supply- )ipe receiving steam from the boiler and i aving'a union-coupling connecting it with said rotative pipe, whereby the latter may turn independently ol' the supply-pipe, and said rotative pipe carrying an angular en wise-closed pipe-section revoluble in a vertical plane and located Within the setting and between itand the end of the boiler, and having a series of steam-delivery.perforations through its side toward the mouths of the fines and of greater number than the number of fines in any line radially of the axis of the boiler. i
